Race

Race is the term used by humans to describe their own sub-species divergences. Race exists because of phenotypical and behavioral differences recognized between defined peoples. The four main races understood are aboriginal, negroid, caucasoid, and mongoloid with several other subcategories, mixings, and minor races in addition.

Aboriginal
Homo sapiens aboriginalis is seen as the oldest version of modern humans alive. They've been found to come from Australia and its surrounding islands though symbolic similarities found at Turkish site Göbekli Tepe suggest they may have occupied elsewhere before.

Phenotypically, Aboriginals have dark skin, heavy brows, and large eyes. Most of them were understood to have healthy teeth before the introduction of European foods.

Negroid
Homo sapiens negroidus is native to sub-Saharan Africa and has much genetic influence on the rest of the continent and the Americas and the Mediterranean. They have a recently-growing presence in Europe.

Phenotypically, negroids have dark skin and have a skull shape in between Aboriginals and caucasoids. Pure negroids tend to be tall and lean with much leg muscles making them the world's best runners.

Caucasoid


Homo sapiens caucasus is mostly attributed to those native to Europe (west of the Ural Mountains and north of the Mediterranean).

Phenotypically, caucasoids have variance in pigment (due heavily to mixings along their borders).

Mongoloid


Homo sapiens mongolus is a broad construct encompassing those occupying East Asia and Southeast Asia. Those discovered to be living in the America's at the time of European arrival are also attributed to this identity.

Phenotypically, mongoloids are quickly distinguished by their flat faces and common epicanthal folds and "yellow" skin pigmentation caused by a type of fat storage in the skin.
